Title: [ANN] Stratum support for scrypt mining has been added for cgminer/reaper Post by: tacotime on December 20, 2012, 04:36:25 AM Stratum mining allows LTC pools to achieve less than 0.5% stales. The only current pool to implement it is ltcmine.ru (http://ltcmine.ru/). If you check out their list of miners there, you will see that many are mining with quantities of stales as low as 0.2%.
Latest version of cgminer to support it is 2.10.2 The reaper version that supports stratum is here: https://bitcointalk.org/index.php?topic=92522.msg1372243#msg1372243 I think as a community we work on getting stratum support for more pools, so that you guys pool mining all get more litecoin. Currently, PoolServerJ supports both litecoin mining and stratum. Title: Re: [ANN] Stratum support for scrypt mining has been added for cgminer/reaper Post by: Nicksasa on December 20, 2012, 10:44:47 AM What ? As far as I know, the official poolserverj has no stratum support and scrypt support is still broken.
Title: Re: [ANN] Stratum support for scrypt mining has been added for cgminer/reaper Post by: tacotime on December 20, 2012, 04:05:33 PM Isn't poolserverj the backend for ltcmine.ru? Unless I'm mistaken
Title: Re: [ANN] Stratum support for scrypt mining has been added for cgminer/reaper Post by: Balthazar on December 21, 2012, 08:19:10 AM No, we are not using poolserverj for ltc pool.
Don't know about cgminer, but our stratum-mining-proxy fork works fine. There is a mistake in first post, our reaper fork doesn't support stratum for now, and i recommend to use it in combination with our proxy. But it's planned to implement native support. Title: Re: [ANN] Stratum support for scrypt mining has been added for cgminer/reaper Post by: Balthazar on December 21, 2012, 10:54:56 AM Tested cgminer 2.10.2, and it's doesn't work. So, our mining-proxy is the only way to mine through stratum/ltc, for now.
P.S. I've planned some changes in LTC version of stratum protocol, to make it more correct and clear (in terms of difficulty, for example).

Care to explain why cgminer natively doesn't work? Is the problem in cgminer or the pool's stratum implementation?Title: Re: [ANN] Stratum support for scrypt mining has been added for cgminer/reaper Post by: Balthazar on December 21, 2012, 11:34:35 AM Tested cgminer 2.10.2, and it's doesn't work.

if you are getting high stales make sure you are using the mining proxy!

It's a new low bandwidth network implementation for mining. It also reduces stales as it takes way less time for work to be sent to mining nodes. One of the problems with the litecoin network over the old JSON protocol is the time it takes to send new work to mining clients when a new block is found. The protocol was designed to facilitate high throughput mining operations on the bitcoin network but works well for the litecoin network too. |
